Replacement of high-efficiency air filters in operating rooms, how long do high-efficiency filters usually need to be replaced, replacement cycle of high-efficiency filters, installation of high-efficiency filters, and manufacturer of high-efficiency filter replacement.

1、 After using the operating room for a certain period of time, there will be varying degrees of pollution. In addition to daily maintenance, regular monitoring should be carried out according to relevant regulations to ensure that the cleanliness of the operating room is qualified, thereby ensuring that the prepared preparations are qualified.

2、 Preparation for the operating room

Determination of the minimum number and location of sampling points; Suspended particle count test; Sedimentation bacterial count test; Sampling method; Cultivation; The comprehensive indicators of the BCJ-1D laser dust particle counter for colony counting comply with the national standard (GB6167. I-85), with a minimum test particle size of 0.3 O, m and an air sampling volume of 2.83 L/min. The instrument uses 0.3 O for self-cleaning, and the total count in the m range is zero for three consecutive times (1 min/time), requiring less than 10 minutes, Real time observation of the counting situation of any channel can be carried out. The main sources of pollution inside the operating room are people, objects, equipment, etc., accounting for about 90%. The filtration method is widely used due to its high capture rate and economy. Most particles in the air can be filtered out. Therefore, a normal operating room is almost sterile or meets the standards. Laser dust particle counters are often used for monitoring. The replacement cycle of high-efficiency air filters is generally 1-2 years, and the replacement cycle of primary filters should be shorter. The replacement cycle of high-efficiency air filters is not fixed and should be determined according to the air quality, frequency and time of use, and monitoring results of their usage environment. It is better to replace them when the test results are close to the test standards. It is necessary to ensure that the surgical operation is carried out. The room cleanliness is qualified while avoiding unnecessary waste.

3、 After thoroughly filtering the clean operating room with a purified air system, the natural settling method is used for sampling and cultivation, which meets the requirements of Class I air purification and provides safety assurance for surgery. After purifying the clean operating room, it can only reduce or eliminate bacteria in the air, and cannot achieve the effect of adsorbing dust and sterilizing clothes. Therefore, strict management of the hygiene of clean operating rooms, implementation of air purification, regular care, maintenance of indoor clean areas, control of pollution sources, and reduction of bacterial infections are particularly crucial.
4、 In short, the management of clean operating rooms is crucial, and effective, scientific, and strict management plays a key role in ensuring medical quality and controlling infections.

High efficiency filters include non partition high-efficiency filters and partition high-efficiency filters, high-temperature resistant high-efficiency filters, combined sub high efficiency filters, and ultra high efficiency filters,DOPEquipped with liquid tank type high-efficiency filter and knife holder type high-efficiency filter (dense pleated high-efficiency filter)/Combination high air volume high-efficiency filterULPAUltra efficient filter.

High efficiency filters are widely used in industries such as electronics, semiconductors, precision machinery, pharmaceuticals, hospitals, and food, which require high cleanliness for end filtration in civilian or industrial clean spaces.
